Which ones match the answers?

Answers

LCM:10:  0,10,20,30,40,504:  0,4,8,12,16,20ANSWER IS 20LCM:10:  see above numbers6:  0,6,12,18,24,30ANSWER IS 30So, 10 and 8 would be 40

Answer:Step-by-step explanation:We have to find the LCM of the given numbers and match then with their options given.LCM of 10 and 4factors of 10 = 2 × 5factors of 4 =  2 × 2LCM = 2 × 5 × 2 = 20         Matches (C)LCM of 10 and 6factors of 10 = 2 × 5factors of 6  = 2 × 3LCM = 2 × 3 × 5 = 30           Matches (A)LCM of 10 and 8factors of 10 = 2 × 5factors of 8 = 2 × 2 × 2LCM = 2 × 5 × 2 × 2 = 40      Matches (B)
